Three nitrogen-doped graphene samples were synthesized by the hydrothermal method using urea as doping/reducing agent for oxide (GO), previously dispersed in water. The mixture was poured into an autoclave and placed oven at 160 °C 3, 8 12 h. correspondingly denoted NGr-1, NGr-2 NGr-3. effect of reaction time on morphology, structure electrochemical properties resulting materials thoroughly investigated scanning electron microscopy (SEM) Raman spectroscopy, X-ray powder diffraction (XRD),...
A kinetic model of spontaneous amplification enantiomeric excess in the autocatalytic addition diisopropylzinc to prochiral pyrimidine carbaldehydes is extended by a negative feedback process. Simulations based on result large-amplitude oscillations both continuous-flow stirred tank reactor (CSTR) and semibatch configuration under optimized initial conditions. When sustained are maintained CSTR, no product distribution could be observed calculated series; system keeps its ratio endlessly....
Novel isoxazole–triazole conjugates have been efficiently synthesized using 3-formylchromone as starting material according to a multi-step synthetic approach. The structures of the target and intermediate products were characterized by standard spectroscopic techniques (1H NMR 13C NMR) confirmed mass spectrometry (MS). all-synthesized compounds screened for their antibacterial activity against three ATCC reference strains, namely Staphylococcus aureus 25923, BAA-44, Escherichia coli 25922...
The nun moth, Lymantria monacha L. (Linnaeus, 1758), is one of the most important defoliators coniferous forests in Europe and Asia. In sexual communication, females produce three epoxides an alkene: (−)-disparlure [(7S,8R)-cis-7,8-epoxy-2-methyloctadecane], (+)-monachalure [(7R,8S)-cis-7,8-epoxyoctadecane], (−)-monachalure [(7S,8R)-cis-7,8-epoxyoctadecane], their corresponding olefins. This study aimed to develop a green synthesis pathway for all pheromonal components, emphasizing use...
Milk and dairy products are considered the main sources of saturated fatty acids, which a valuable source nutrients in human diet. Fat composition can be adjusted through guided nutrition animals but also selective breeding. Recently, dinucleotide substitution located exon 8 gene coding for acyl CoA: diacylglycerol acyltransferase 1 (DGAT1), that alters amino acid sequence from lysine to an alanine (p.Lys232Ala) mature protein, was shown have strong effect on milk fat content some cattle...
The resurgence of mead, a honey-based fermented beverage, is attributed to the increasing consumption foods and beverages, driven by its distinct flavors perceived health benefits. This study investigates influence different yeast strains, namely Saccharomyces cerevisiae var. bayanus, Torulaspora delbrueckii, on volatile phenolic compounds these beverages. Analytical techniques, including HPLC-DAD GS/MS, were employed analyze chemical composition ANOVA analysis variance was conducted assess...
The aim of this work was to compare the variations alcohols compounds in white wine Muscat Ottonel variety aged presence untoasted oak chips, toasted chips and barrel, considering three ageing periods—30, 60, 90 days. liquid-liquid extraction gas chromatography coupled mass spectrometry were used concentrations volatile constituents wines. A total 51 quantified. Alcohols, terpenic carboxylic acids decreased with time, whereas esters, lactones, phenolic increased due esterification processes....
Enantiomeric excesses obtained in absolute enantioselective synthesis by chiral autocatalysis (Soai-reaction) were statistically analyzed. Two sets of parallel experiments, which performed under chemically different conditions, are available. One group contains 37, while the other 84 preparative results. The former shows some interesting tendencies but does not give conclusive statistical sample providing 39 R- and 45 S-excesses have shown that these data represent two distinct,...
A series of novel functionalized mono-, bis- and tris-(S)-{[(2S,4R,8R)-8-ethyl-quinuclidin-2-yl](6-methoxyquinolin-4-yl)}methanamines including ferrocene-containing derivatives was obtained by the reaction precursor amine with a variety acylation agents. Their in vitro antitumor activity investigated against human leukemia (HL-60), neuroblastoma (SH-SY5Y), hepatoma (HepG2) breast cancer (MCF-7) cells 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT)-assay 50% inhibitory...
Ferulic acid decarboxylase from Saccharomyces cerevisiae (ScFDC1) was described to possess a novel, prenylated flavin mononucleotide cofactor (prFMN) providing the first enzymatic 1,3-dipolar cycloaddition mechanism. The high tolerance of enzyme towards several non-natural substrates, combined with its quality, atomic resolution structure nominates FDC1 an ideal candidate as flexible biocatalyst for decarboxylation reactions leading synthetically valuable styrenes. Herein substrate scope...
Novel (N-arylamino)phenothiazinium dyes containing meta-substituted-arylamine auxochrome units were successfully obtained by applying a sonochemical protocol designed for more efficient energy usage in the preparation of methylene blue (MB) analogues. Single crystal X-ray diffraction analysis revealed spatial arrangement aggregated crystalline state (N-(meta-bromoaryl)amino)phenothiazinium dye with minor variances induced nature halogenide counterion (iodide or chloride). The optical UV-vis...
Selenium is an essential element for the well-being of humans and animals. Micronutrient deficiencies affect over half global population. Biofortification crops with selenium represents economically sustainable solution to combat this problem. In study, seven Allium species underwent Se biofortification, via soil enrichment selenate in pots, at three distinct concentration levels were used explore relationship between plant internalization, polyphenol composition, mineral content. chosen...
The effluents of the sugar and bio-ethanol industry, mainly vinasse as well lignocellulosic waste, are produced in high volumes. Therefore, their treatment valorization would reduce environmental impact make this industry more productive competitive. purpose study was to determine potential use press mud (lignocellulosic waste), powder, sludge from an extraction process with ethanol, raw materials for conventional pyrolysis evaluating physicochemical characteristics that affect...
L-polylactic acid (PLA), a semi-crystalline aliphatic polyester, is one of the most manufactured biodegradable plastics worldwide. The objective study was to obtain (PLA) from lignocellulosic plum biomass. Initially, biomass processed via pressurized hot water pretreatment at temperature 180 °C for 30 min 10 MPa carbohydrate separation. Cellulase and beta-glucosidase enzymes were then added, mixture fermented with Lacticaseibacillus rhamnosus ATCC 7469. resulting lactic concentrated purified...
